The Omega Products HSK63F ER Collet Chucks are precision toolholders built for high-speed machining. Designed with an HSK63F shank, they deliver the rigidity and accuracy essential for demanding milling operations. With a G2.5 runout and a top-end speed of 25,000 RPM, these chucks minimize tool deflection and vibration to improve surface finish and extend tool life. The ER16 collet system clamps a broad range of tool diameters, providing versatility across different applications, and the 160 mm gauge length supports reliable, repeatable performance in a variety of setups. G2.5 Runout for Consistent Results: Minimizes tool deflection and vibration, delivering smoother finishes and longer tool life even at high speeds. Rigid HSK63F Shank: Provides superior rigidity and accuracy during machining, helping maintain tight tolerances under demanding conditions. ER16 Collet System for Versatility: Clamps a wide range of tool diameters, enabling quick setup changes and broad applicability across milling tasks. This toolholder is built to boost productivity by delivering precise, stable performance at up to 25,000 RPM, reducing downtime and ensuring repeatable results across jobs. Its robust construction and compatible gauge length integrate smoothly into a wide range of high-speed machining setups, helping you achieve reliable performance every shift.
